Tracing the merger history of MACS clusters using the GMRT
S. Paul, A. Datta, H. T. Intema
Galaxy-cluster merger shocks efficiently accelerate the ambient electrons through diffusive shock acceleration and amplify magnetic field by compressing the Inter Cluster Medium. A…
New insights from deep VLA data on the potentially recoiling black hole CID-42 in the COSMOS field
Mladen Novak, Vernesa Smolcic, Francesca Civano +12
We present deep 3 GHz VLA observations of the potentially recoiling black hole CID-42 in the COSMOS field. This galaxy shows two optical nuclei in the HST/ACS image and a large vel…
Measurements of the Sunyaev-Zel'dovich Effect in MACS J0647.7+7015 and MACS J1206.2-0847 at High Angular Resolution with MUSTANG
Alexander H. Young, Tony Mroczkowski, Charles Romero +18
We present high resolution (9) imaging of the Sunyaev-Zel'dovich Effect (SZE) toward two massive galaxy clusters, MACS J0647.7+7015 () and MACS J1206.2-0…
A giant radio halo in the cool core cluster CL1821+643
A. Bonafede, H. T. Intema, M. Brüggen +8
Giant radio halos are Mpc-size sources found in some merging galaxy clusters. The synchrotron emitting electrons are thought to be (re)accelerated by plasma turbulence induced by t…
Spectroscopic Confirmation of an Ultra Massive and Compact Galaxy at z=3.35: A Detailed Look at an Early Progenitor of Local Most Massive Ellipticals
Z. Cemile Marsan, Danilo Marchesini, Gabriel B. Brammer +10
We present the first spectroscopic confirmation of an ultra-massive galaxy at redshift z>3 using data from Keck-NIRSPEC, VLT-Xshooter, and GTC-Osiris. We detect strong [OIII] and L…
Filaments in the southern giant lobe of Centaurus A: constraints on nature and origin from modelling and GMRT observations
Sarka Wykes, Huib T. Intema, Martin J. Hardcastle +8
We present results from imaging of the radio filaments in the southern giant lobe of Centaurus A using data from GMRT observations at 325 and 235 MHz, and outcomes from filament mo…
